The ferromagnetic systems CePd(1-x)Rh(x), ZrZn2 and Fe(1-x)Cr(x) were investigated which undergo different types of quantum phase transitions. Experiments were done using a newly designed set up for neutron depolarisation measurements which enables to investigate the effect of pressure and magnetic fields at lowest temperatures, spatially resolved over a sample. Furthermore, a wavelength-frame multiplication chopper-system was designed and optimised using simulations. The chopper-system is foreseen to be installed at the future neutron-imaging instrument ODIN at ESS.
